AK No Ka Oi - 120-84-110 @ 193. Stiffer than Rex & G4's...Not sure about direct comparison to Stockli's though. Very fast and stable..great high-speed crud buster. Very turny though so if you want a straighter ski look elsewhere...www.akski-usa.com
Can't go wrong with Iggies of course as Bob suggested, but I think the skinniest ski they offer now is the FatGS with an 88 waist. They might make something custom for ya though....
And of course, I'm partial to the PM Gear Bro Model (thanks for the suggestion Gonzo)...but it's a 99mm waist. Not exactly what you are asking for here....but check 'em out anyway www.pmgearusa.com
